Description

The invention relates to electrical equipment of vehicles and can be used in devices for signaling a change in maneuver.

The purpose of the invention is to increase the information content.

The drawing shows a block diagram of the device.

The device contains lamps 1, 2 direction indicators, the supply circuit of which includes key elements 3, 4, the information inputs of which are connected through the control relay 5 with contact 5.1 to the output of the flash frequency setting unit 6. Unit 6 is connected to a series-connected multivibrator 7 and a thyristor switch 8. The control inputs of the elements 3, 4 are connected to the outputs of the RS flip-flops 9, 10, one of the inputs is connected through the drivers 11, 12 of the pulses to the sensor 13 of the steering wheel position. The outputs of the unit 6 are connected to the lamps 1, 2 via the turn switch 14. The output of the multivibrator 7 of block 6 is connected to the counting input of the pulse counter 15, the setup input of which is connected to the output of the IL-16 element, the outputs of which through the drivers 11, 12 are connected to the sensor 13. The power of the block 6 is supplied through the contacts of the ignition lock 17 and into the power supply circuit control lamp 18 is included contact 5.1 relay 5.

Sensor 13 is designed so that its corresponding contacts close when the steering wheel is rotated 30-45 ° to the left or right of the initial position.

The device works as follows.

When the ignition lock 17 is turned on, the multivibrator 7 of block 6 is started, the pulses of which are fed to the input of the counter 15. At the output of the counter 15, every fourth pulse appears, which sets the triggers 9 and 10 to the initial state.

When the ignition lock 17 is turned on, the pulses 6 are formed at the output of the block 6, and the lamp 1 or 2 comes through the switch 14 when it is installed in the appropriate position, causing them to flash, which indicates that the vehicle has made a turn. At the same time, the lamp 18 flashes at the same frequency (contact 5.1 of relay 5 periodically closes), signaling to the driver about the operation of the direction indicators. The contacts of the sensor 13 are open, resulting in the elements 3, 4 are closed by signals from the outputs of the trigger 9,10.

Turning the steering wheel to the left by 30-45 ° from a rectilinear motion causes the corresponding contacts of the sensor 13 to close, as a result of which the driver 11 generates a pulse, which sets the counter 15 to its initial state through the element OR 16 and puts the trigger 9 into a state in which a signal appears at its output, opening element 3.u

On this signal, the element 3 connects to the output of the block b through the relay 5 lamp 1 left

side of the vehicle that will start blinking. After three flashes at the output of counter 15, a pulse is generated that sets trigger 9 to its initial state.

Element 3 closes and lamp 1 stops blinking.

Similarly, the device works when you turn the steering wheel to the right.

Thus, the device provides an automatic signaling of the maneuver of the transport system when the steering wheel is rotated 30-45 °, regardless of the setting of the switch 14 to the appropriate position.
